I also observed and photographed the two objects in Cygnus. The brighter object appulsed xi Cyg quite close in the direction of Deneb 19:23:40. This is 2m 03s after the prediction from the elset below !? I obtained four pictures in Cygnus (one with only the trailer), one in Cephei, and witnessed a flare at about mag -4 about 5 deg below Polaris. 2013/8/28 Ted Molczan <ssl3molcz@rogers.com> > Cees Bassa sent me the positions that reduced from his photos of two > objects from the launch of NROL-65. > > 99066 13 740A 4171 G 20130828192053736 17 25 2254497+111506 37 S > 99066 13 740A 4171 G 20130828192059697 17 25 2256784+121339 37 S > 99066 13 740A 4171 G 20130828192106706 17 25 2259528+132258 37 S > 99067 13 740B 4171 G 20130828192100486 17 25 2254301+113284 37 S > 99067 13 740B 4171 G 20130828192109706 17 25 2257760+130290 37 S > > Object 99066 was leading 99067. > > My guess is that the fainter, trailing object 13740B, is the payload, and > the brighter leading object is the second > stage of the Delta 4H. > > Here are updated elements fit to 13740B: > > 1 79502U 13240.80636574 .00019623 00000-0 18973-3 0 07 > 2 79502 97.9398 305.0356 0517992 211.7239 199.4683 14.80970130 03 > > Epoch is the time of the observation.
